The skincare industry has a vested interest in selling you more products. Your skin, meanwhile, has a vested interest in you using fewer of them. Research and dermatological consensus both suggest that most people would get better results — and fewer reactions — from a streamlined 3–5 product routine than from the complex 10-step stacks popularised on social media.
For most people, 3–5 products per routine is optimal. The non-negotiables are cleanser, moisturiser, and SPF. Targeted actives (1–2 maximum) can be added based on your specific skin concerns. More than 7–8 products raises the risk of ingredient conflicts and barrier damage.
A minimal routine is easier to maintain consistently — and consistency is the variable that matters most in skincare. It's more affordable. It reduces the risk of ingredient interactions, contact dermatitis, and barrier disruption. And critically, it makes troubleshooting straightforward: when you have four products and your skin reacts, you can identify the culprit. When you have twelve, you cannot.
Dermatologists frequently observe that patients with the most reactive, sensitised, and barrier-compromised skin are often the heaviest product users. More products mean more potential irritants, more disruption of the skin microbiome, and more opportunity for things to go wrong.
If you do only these three things consistently, your skin will be better protected than most people's, regardless of anyone else's routine complexity.
Once your barrier is healthy and the core three are established habits, you can introduce targeted actives. Each active you add should address a specific, real concern. A sensible active stack for most people: one antioxidant serum (vitamin C, morning) plus one repair ingredient (retinol or exfoliating acid, at night — not both simultaneously). That's five products total: cleanser, vitamin C, moisturiser, SPF, and retinol or acid. This addresses the vast majority of concerns — ageing, texture, brightness, protection — without overloading the skin.
Most dermatologists advise caution above 6–7 products per full day. Beyond this, active ingredients can compete, occlusives can prevent thinner products from absorbing, and cumulative irritation potential grows with each addition. Red flags: skin that feels constantly sensitised; products that used to work well seem to have stopped; difficulty identifying the cause of a reaction. If this sounds familiar, a skincare "reset" — returning to just the core three for 4–6 weeks — can help the barrier recover and give you a clean baseline to rebuild from.
